# Bulk Processing

### About Bulk Processing

Bulk Processing (batch processing) lets you **bulk upload customers** and run **batch AML screening checks** in the ComplyCube Portal.

It’s a **no-code** solution designed for businesses of all sizes. Use it to import large client datasets into ComplyCube via **CSV upload**, whether for **migration purposes** or to run periodic **batch AML screenings** with **continuous monitoring**.

{% hint style="info" %}
This service has a **soft limit** of 1,000 clients per batch. Get in touch with your **Account Manager** to increase it.
{% endhint %}

{% hint style="info" %}
ComplyCube is also capable of processing files in bulk through **Secure File Transfer Protocol (SFTP)**. Get in touch with your **Account Manager** to enable this method.
{% endhint %}

### Common use cases

Use Bulk Processing when you need to run compliance checks across a large dataset:

* **Customer migration**: Upload existing customers from another system during migration.
* **Audit & remediation runs**: Run a bulk [AML screening check](https://docs.complycube.com/documentation/product-guides/watchlist-pep-and-adverse-media/aml-screening-check) to validate or remediate a large set of customers after data corrections, rule changes, or an internal audit.
* **Internal list matching**: Combine with [Custom Lists](https://docs.complycube.com/documentation/product-guides/watchlist-pep-and-adverse-media/custom-lists) to screen against proprietary watchlists.
